Banned terrorist outfits such as Babbar Khalsa International (BKI) are trying to revive Sikh militancy, the union government said on Tuesday, citing intelligence reports.

"There are reports that some organisations such as the BKI in the UK are striving to revive Sikh militancy," minister of state for home affairs RPN Singh told the Lok Sabha in a written reply, adding that the government was keeping a close watch on their activities.

The government has conveyed its concerns to the UK authorities on various occasions, including during the recent India-UK summit held here last month. "Both sides have agreed to enhance cooperation in this regard," he said.
